[PATCH 21/38] arm64: dts: mediatek: mt6795-sony-xperia-m5: Add pinctrl for mmc1/mmc2

[AngeloGioacchino Del Regno]

Add pinctrl nodes for the MicroSD slot on mmc1 and SDIO Controller
on mmc2 and assign those to the respective controller nodes.
This makes sure that all of the pins are muxed in the right state
and with the right pullup/down(s) before trying to use the mmc
controllers.
